🔇Windows中实现锁屏自动静音
需求
防止我在梦中惊醒，一怒之下整了这个脚本
实现
- 实现锁屏静音🔇，解锁恢复
- 锁屏前就是静音状态，则解锁保持静音🔇
- 接住AudioDeviceCmdlets模块，运行几乎无压力
代码
把下面代码用自带记事本保存，文件名（包括扩展名）改成 SetupMuteOnLock.ps1 并使用管理员权限运行。
# 需要以管理员权限运行
if (-not ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
Write-Host "请以管理员权限运行此脚本！" -ForegroundColor Red
Start-Sleep -Seconds 3
exit
}
Write-Host "正在设置锁屏自动静音功能..." -ForegroundColor Green

if (-not (Test-Path -Path $scriptDir)) {

if (-not $moduleInstalled) {

Install-Module -Name AudioDeviceCmdlets -Force -Scope CurrentUser
Write-Host "AudioDeviceCmdlets模块安装成功！" -ForegroundColor Green
